Laser cladding technology and turbine repair analysis

In today's turbulent economic era, we naturally hope that large investments can be as effective as possible for as long as possible and are worth the money. This is especially true for industrial gas turbine components. The manufacture and replacement of components is very expensive, so it is necessary to use efficient maintenance techniques to protect investment. The main purpose of industrial gas turbines is to generate electricity, and can also be used to drive compressors. In addition, they can also be used to drive oil pumps in certain environments, such as oil drilling platforms and oil fields.　　 High-value parts are placed behind the combustion chamber, where the parts have to withstand the extremely high temperatures of the hot gas. The hot gas channel components are made of high-temperature super alloy with nickel as the base material. However, the robustness of super alloys makes it difficult or even impossible to repair this material through traditional welding processes. Although there are various coating technologies that can be used to repair and repair these components, laser cladding is becoming the preferred method because of its highly localized heat input, widely available materials, and the weldability of heat-sensitive materials. improved. In the past 15 years, technicians have increasingly introduced automated laser cladding processes when repairing turbine components, rather than manual traditional welding processes such as tungsten argon arc welding (TIG). In fact, industrial gas turbines and aero engines are precisely the application industries driving the innovation of laser cladding.
